Liquid tank and support

ABSTRACT

An auxiliary tank for a liquid is removably mounted on a rod extending from a support attached to selected threaded studs supporting a spare tire on a vehicle. A plurality of snaplock elements retain the tank locked with the support. A second tank for a liquid may be mounted on the rod adjacent the first tank. A further plurality of snaplock elements interlock the two tanks with one another. To prevent unauthorized removal of the tank(s), a conventional padlock is engaged with a passageway at the end of the rod. A variant support includes a flange for attachment to a bumper, running board, or the like, of a vehicle.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to liquid tanks and, more particularly, to liquid tanks and supports for mounting same.

2. Description of Related Prior Art

Various types of vehicles are used in conjunction with off-road travel. These vehicles may be of a conventional type licensed for use on state highways. An example of a commonly used vehicle of this type is known as a Jeep. Jeeps used for this purpose may be either stock or modified and/or adapted for boulder strewn terrain or sand dunes. Modifications for these purposes generally include oversize tires, suspension modifications and guards to protect the engine, the differential(s), and the transmission from contact with the terrain.

Numerous types of vehicle specifically built for off-road use have been developed over the years. Generally, these types of vehicles are not licensed for conventional road use.

Depending on the terrain to be traversed, more powerful engines may be substituted for conventional engines in licensed vehicles. For the off-road type vehicles, powerful engines are generally used to provide both high speed and the power to navigate steep hills or very rough terrain.

The powerful engines used have a high rate of gas consumption. For extended off-road excursions, gasoline in excess of the capacity of the fuel tank mounted therein may be required to ensure that the destination is reached. Conventionally, additional gasoline may be carried in gas containers of the surplus military type known as 5 gallon Jerry cans. A mounting bracket for each Jerry can includes a shelf with a perimeter lip to support the bottom of the Jerry can and one or more straps envelop the midsection of the Jerry can to prevent disengagement. While this mode of transporting extra gas is relatively inexpensive, there are some drawbacks. The location for attaching the mounting generally impedes or restricts movement of passengers. Moreover, it may serve as an impediment for loading and unloading supplies and the like. Furthermore, a fire hazard may be created if the vehicle rolls and causes the Jerry can to burst.

SUMMARY OF THE INVENTION

The present invention is directed to a support mountable on a vehicle for removably supporting one or more liquid tanks. A rod extends from the support through penetrable engagement with each liquid tank. Snaplock elements engage the liquid tank with the support. One or more further liquid tanks may be mounted on the rod. Further snaplock elements secure each further liquid tank with a previously mounted liquid tank to accommodate a plurality of detachably attached liquid tanks mountable on the rod of the support. Each of these liquid tanks may be filled with gasoline, water, or other fluid that may be anticipated to be needed during travel of the vehicle. A padlock, or the like, engages the tip of the rod extending from the support to prevent unauthorized removal of a liquid tank.

It is therefore a primary object of the present invention to provide one or more liquid tanks detachably attached to a support.

Another object of the present invention is to provide a support and one or more liquid tanks mounted thereupon for use with an off-road vehicle.

Still another object of the present invention is to provide snaplock elements for lockingly engaging a liquid tank with a support.

A further object of the present invention is to provide snaplock elements for securing two or more liquid tanks to one another and to a support.

A yet further object of the present invention is to provide a support for one or more liquid tanks detachably attached to the threaded studs for supporting a spare wheel of a vehicle.

A still further object of the present invention is to provide a support having a rod penetrably engaging one or more liquid tanks and mountable upon a vehicle.

A yet further object of the present invention is to provide a method for supporting one or more liquid tanks on a vehicle.

These and other objects of the present invention will become apparent to those skilled in the art as the description thereof proceeds.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, there is shown a conventional vehicle of the type often used for on-road and off-road travel. A representative vehicle of this type is sold under the name Jeep. It usually includes a spare wheel 12 mounted on threaded lugs extending from a rear panel of vehicle 10. These lugs may also be used to mount a support for one or more removable liquid tanks 14. As represented by dashed lines 16, 18, the liquid tank may be removed rearwardly or mounted forwardly. Such liquid tanks are usually mounted on an off-road vehicle or a vehicle to be taken off-road and contain fuel, such as gasoline or diesel fuel, to ensure that the vehicle is unlikely to become stranded by running out of fuel. As will be described below, more than one liquid tank may be mounted. In such case, the second or further liquid tanks may contain either fuel or water for purposes of survival or to replenish the liquid in the radiator of the vehicle. It is to be understood that any type of liquid may be contained within a liquid tank. For purposes of clarity and simplicity, the liquid tank will be referred to simply as a tank.

Referring jointly to FIGS. 2, 3, 3A and 4, details attendant the support for tank 14 will be described. Spare wheel 12 is mounted on vehicle 10 through a plurality of studs extending through mounting holes and threadedly engaged by nuts 22, as is conventional. A support 24 for the liquid tanks includes studs 26. Each stud includes a threaded end 28 for engagement through an aperture in support 24 and secured thereto by a nut 30 and a washer 31. The other end of the stud includes a threaded cavity 32 for engagement with a respective one of studs 20 extending from the vehicle. For stability purposes, three studs may be used, as illustrated.

A rod 34 is attached to and extends from support 24. It is secured to the support by a nut 36 and a washer 38 threadedly engaging end 40 of the rod. Free end 42 of the rod may include a passageway 44 for engagement by the hasp of a conventional padlock 46. As shown in FIG. 2, tank 14 includes a passageway 48 extending therethrough for penetrably receiving rod 34.

As will be described in further detail below, snaplock elements positionally secure tank 14 with support 24. Moreover, such snaplock elements secure one tank to another tank also mounted on rod 34. As illustrated in FIG. 4, three male components 50 of three snaplock elements are mounted on support 24 by pairs of screws or bolts 52, 54. Similarly, three female components of the three snaplock elements, of which only one female component is shown in FIG. 3, are mounted on the rear surface of tank 14 to engage a respective one of the male components on the support.

Referring jointly to FIGS. 5, 6, 7, 8 and 9, features attendant tank 14 will be described. Tank 14 includes a cap 60 of the conventional type for threaded engagement with outlet conduit 62 disposed at the top of the tank. A flexible arm 64 extends from cap 60. This arm comes into interfering relationship with stop 66 disposed at the top of the tank. Upon pressing flexible arm 64 toward the cap, it will clear stop 66 and permit unscrewing of the cap and access to outlet conduit 62. As particularly shown in FIGS. 6 and 7, rear side 70 of tank 14 includes female components 72. Each of these female components engages, in a snaplock manner, with a respective one of male components 50 disposed on support 24. As shown in FIGS. 8 and 9, front side 74 of tank 14 includes male components 50. When two or more tanks are stacked adjacent one another on rod 34, these male components engage the corresponding female components on the adjacent tank previously mounted on the rod. Thereby, the tanks are lined with one another through penetrable engagement by rod 34 and adjacent tanks are locked with one another.

FIGS. 10, 11 and 11A illustrate a variant support 80. Many vehicles taken off-road are of a type other than the Jeep-like vehicle shown in FIG. 1. These vehicles may not have studs for engagement by a spare wheel and support 24, as shown and described above. To mount tanks 14 on such a vehicle, variant support 80 may be used. The variant support includes a base 82, which may be a flat section of steel or other relatively robust material. A platform 84 extends from base 82 at an angle of 90 degrees, as shown, or at another angle more suitable for the location to which the variant support is to be attached. Gussets 86 may be incorporated to more robustly secure the base with the platform. As particularly illustrated in FIG. 10, base 82 may be attached to a flat surface 88 such as a section of a bumper on the vehicle. However, surface 88 could be any other surface on the vehicle which would lend itself to attachment of the variant support and the tanks mounted thereon. Representatively, bolts 90 extend through base 82 and surface 88 to secure them with one another by nut 92. A rod 34, like rod 34 shown in FIGS. 2 and 3, is secured to platform 84 by a nut 94 and a washer 96 to threaded end 40 of the rod. As shown in FIGS. 10 and 11, male components 50 of three snaplock elements are attached to platform 84 for engagement with female components 72 of a tank to effect an interlock. A lock, which may be a conventional padlock 98, engages a passageway 44 of rod 34 to prevent removal of tank or tanks 14 from the variant support. As particularly shown in FIG. 11, a second tank is illustrated in dashed lines and represents the possibility of mounting two or more tanks on either support 24 or on variant support 80.

Referring jointly to FIGS. 12 through 17, details and operation of the male and female components constituting a snaplock element will be described in detail. FIGS. 13 and 14 illustrate female component 72 of the snaplock element disposed in rear side 70 of a tank. The female component is formed by an essentially rectangular depression 100 in the rear side. It includes a pair of shelves, of which shelf 102 is illustrated. Each of these shelves supports one of flanges 104, 106. Each of the flanges is secured to the tank by screws or bolts 110 extending through a hole in the respective flange and into threaded engagement with depression 100 in the respective shelf. A circular dimple 114 is formed in the base of depression 100 and essentially centered upon the space between the opposed flanges, as illustrated in FIG. 13. A curved channel 108 extends from depression 100 to the edge of the tank, as illustrated, for example, in FIGS. 6 and 7. The purpose of this slot is to accommodate passage therealong of a part of the male component.

Male component 50 of a snaplock element is primarily illustrated in FIGS. 15 and 16. A depression 116 is formed in front side 74 of the tank. The male component is disposed therein and secured in place by a screw or bolt 118 in penetrable engagement with hole 120 in the male component and into threaded engagement with a cavity 122. Base 124 of the male component supports an extension 126 T-shaped in cross-section. That is, an upright section 128 extends from base 124 to support a cross member 130. The surface of the cross member includes one or more buttons 132 extending therefrom. As shown in FIG. 17, a button 132 mates with dimple 114 upon engagement of the male component with the female component and thereby discourages disengagement therebetween. It is to be noted that the width of cross member 130 is somewhat less than the width of channel 108 to permit sliding engagement of the cross member therealong.

FIG. 16 is a partial cross-sectional view of male component 50 in engagement with female component 72. To lock one tank with another tank or to lock a tank to either support 24 or variant support 80, a first tank is mounted upon rod 34 at an angle 140 (see FIG. 12) necessary to locate cross member 130 of each male component 50 within a corresponding one of channels 108. By rotating the tank relative to the support or the variant support through angle 140, cross member 130 extends into depression 100 of female component 72 and beneath the opposing edges of the respective pair of flanges 104, 106, as shown in FIG. 16. On completion of the insertion of male component 50 within female component 72, button 132 will come into engagement with dimple 114, as shown in FIG. 17. This mating of the button with the dimple will not prevent but will restrain disengagement of the tank from either the support or the variant support.

A similar process is employed to engage a second tank with a first tank already mounted on rod 34 and in engagement with a respective support. The second tank is slid onto the rod at a rotational angle with respect to the first tank, as represented by numeral 140. Such orientation will place the cross member of each of the male components within the respective one of channels 108. Thereafter, the second tank is rotated through angle 140 to bring about locking engagement of the male component with the female component.

The number of tanks to be mounted on rod 34 is simply a function of the length of rod 34. Each of these tanks will be in locking engagement with an adjacent tank and the tank closest to the support or the variant support is in locking engagement therewith.

For storage or other purposes, it is to be understood that two or more tanks may be placed in locking engagement with one another without being mounted on a rod. Such assembly may be particularly useful for storage or transportation purposes whether or not one or more of the tanks is filled with a liquid.

To assist in manipulating a tank whether upon mounting or dismounting the tank from rod 34 or engaging/disengaging one tank with the support or the variant support or with another tank, pairs of channels 150, 152 may be formed in one or more sides of each tank to assist in handling of the tank and to effect rotational movement about the rod and engage or disengage the snaplock elements.
